^I just wanted you to question what you were saying concerning make-ups used to transform caucasian actors into Asians, blacks, arabs and other races and ethnicities. Make-ups have progressed that it is possible to convincingly transform an actor from one race or ethnicity to another. But we seem to immediately reject the idea as offensive because of past culturally and racially offensive portrayals and systemic racial discrimination in hiring practices in Hollywood.
Because if we were to accept your arguments, Alexander Siddig (Siddig El Fadil), should only play arabs and Latin types. Avery Brooks should only play blacks and African Americans.
Remember that Eddie Murphy was able to convincingly play an elderly caucasian Jewish man in Coming to America
